Do I need to fill in any forms when I arrive at the Nepal airport?

I just came back. In fact, entering Kathmandu Airport is very simple. Just fill out an entry form. You can ask the flight attendant for one before getting off the plane. Fill it out before landing on the plane and hand it to the immigration officer along with your passport. (You can basically check the filled-in content in advance on Baidu, which looks a bit like it.) Don’t be too nervous, Nepalese people are really friendly to tourists.
